Electomagentic Compatibility Design & Signal Integrity

Course Length:

3

Cost:

$1495 per person

Summary:

Design for EMC/SI (Electromagnetic Compatibility & Signal Integrity) is our flagship EMC design class. It addresses the control of EMI (Electromagnetic Interference) at the box level through proven design techniques. This three-day course provides a comprehensive treatment of EMC/SI “inside the box.” This includes digital and analog circuits, printed circuit board design, power electronics, I/O treatments, mechanical shielding, and more. Please note – this class does NOT address “outside the box” issues such as cable design, power wiring, and other systems level concerns. Day 3 discusses EMI Troubleshooting Guidelines with case studies. Each student will receive a copy of the EDN Magazine Designer’s Guide to EMC by Daryl Gerke and William Kimmel, along with a complete set of lecture notes.

What you will learn:

How to identify, prevent, and fix over 30 common EMI/EMC problems in at the box/design level

Simple models and “rules of thumb” and to help you arrive at quick design decisions (NO heavy math).

Design impact of various EMC specifications

Practical tools, tips, and techniques

Good EMI/EMC design practices
